3 -carlsons milled(磨粉) it themselves. however, until last year there was not a single ethiopian restaurant or bakery in the entire state of idaho for them to sell the milled flour to. “the way we started was that wayne went through the washington, dc., and looked for the names that were ethiopian in the telephone book.” over time, the teff company has grown out four different mills. the carlsons say the teff flour coming off the mill could end up in a good natural foods store or commercial bakery. “sales of alternatives (替代品) to modern wheat (小麦) are growing quickly each year, ” says an industry trade group. rich roseberg is a food researcher at oregon state university. he says teff production has exploded over the past decade in the us. he also says most teff grown in the us. is fed to farm animals. in idaho, however, where the carlsons are based, roseberg believes more of the teff production is for human food. teff contains lots of calcium, iron, and protein. roseberg praises wayne carlson for being ahead of his time.【语篇解读】埃塞俄比亚画眉草的种子在埃塞俄比亚被用作食物原料，现在这种农作物被引进到了美国。4what did wayne carlson probably want to do after returning to idaho?ato become a farmer.bto do public health work.cto mill grains for a living.dto introduce teff to the us.答案与解析：d推理判断题。根据第三段的“wayne and his wife elisabeth are not farmers, nor do they want to be. so they convinced actual farmers in idaho, oregon and nevada to grow teff.”可推断，wayne carlson 想将这种作物引进美国。5what problem did the couple face at first?atheir milled flour couldnt be sold.bthey didnt know how to mill grains.cthey were not good at doing business.dtheir work wasnt supported by others.答案与解析：a细节理解题。根据第三段的“however, until last year there was not a single ethiopian restaurant or bakery in the entire state of idaho for them to sell the milled flour to.”可知，他们俩所面临的问题就是他们磨的面粉卖不出去。- 4 -6why does roseberg think wayne carlson is ahead of his time?abecause wayne carlson improves the taste of teff.bbecause wayne carlson feeds teff to farm animals.cbecause wayne carlson tries to reduce hunger worldwide.dbecause wayne carlson thinks teff should be used as humanfood.答案与解析：d推理判断题。根据末段的“roseberg believes more of the teff production is for human food. teff contains lots of calcium, iron, and protein. roseberg praises wayne carlson for being ahead of his time.”可推断，是因为 wayne carlson 认为埃塞俄比亚画眉草的种子应该被人食用的缘故。c cthe national pass walking track is in the blue mountains national park, one of the most wellknown national parks in australia. it is near wentworth falls, which is around 100 kilometres from sydney (the largest city in australia). it is a circular walking track of 4.4 km. it includes a 709 m climb and takes around 3.5 hours to complete. though the transport is not perfect, the national pass can be readily reached by car or train.the grand stairway is an unforgettable part of the national pass. this is a zigzag stairway (which looks like a line of zs joined together) with 173 steps. it has been described as the tallest outdoor stairway in australia. the grand stairway provides a way to the valley below wentworth falls. it was built around 1906 by workers who used all kinds of different tools.along a great part of this track is the amazing waterfalls which hikers (远足者) pass by, through, and over. these include the empress falls. this is a wonderful waterfall in the valley of the waters. it goes down a series of rocks to a pool. there are stepping stones for hikers to cross the falls and some shady spots where tired travelers can rest.in 2002 the national parks and wildlife service started repair work on the national pass. this work took several years and the project was awarded recognition from unesco (united nations educational, scientific and cultural organization) and the national trust of australia.it is worthwhile to choose a guided tour package for the national pass. the walk costs around $135 per person and requires good health and physical condition. it takes the hiker through valleys, thick forests and ends with a -
